PLS HELP ME WITH THESE TWO QUESTIONS WILL MARK U AS BRAINLIEST !!

Chemistry
1 answer:
Degger [83]3 years ago
4 0

Answer:

See explanation

Explanation:

From the parameters provided;

V=?

n= 1.46 moles

P= 0.982 ATM

T= 13°C + 273 = 286 K

R = 0.0821 L.atm/mol.K

From

PV= nRT

V= nRT/P

V= 1.46 × 0.0821 × 286/0.982

V= 34.9 L

b) Boyle's law states that, the pressure of a given mass of gas is inversely proportional to its volume at constant temperature and pressure. This statement is a correct postulation about ideal gases which can be arrived at from the kinetic theory of gases.

4th one<br> Mark the brainliest
ale4655 [162]

Answer:

1. The electronic configuration of X is: 1s2 2s2 sp6 3s2

2. The configuration of the anion of Y (i.e Y^2-) is 1s2 2s2 2p6

3. The formula of the compound form by X and Y is given as: XY

Explanation:

For X to loss two electrons, it means X is a group 2 element. X can be any element in group 2. The electronic configuration of X is:

1s2 2s2 sp6 3s2

To get the electronic configuration of the anion of element Y, let us find the configuration of element Y. This is done as follows:

Y receives two electrons from X to complete its octet. Therefore Y is a group 6 element. The electronic configuration of Y is given below

1s2 2s2 2p4

The configuration of the anion of Y (i.e Y^2-) is 1s2 2s2 2p6

The formula of the compound form by X and Y is given below :

X^2+ + Y^2- —> XY

Their valency will cancel out thus forming XY
